HANDLE FOR CUTTING-TOOLS, DIE-STOCKS, 8w.

Application filed July 22, 1916.

To all whom it may concern:

Be it known that I, MORRIS GRAMER, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Handles for Cutting-Tools, Die-Stocks, &c., of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

The general object of this invention is to so arrange a handle for cutting tools, such as die stocks, pipe cutters, and the like, that it may serve as a reservoir for oil to be led to the surfaces operated on. More specific objects are to so construct such a handle that it may be simple, eficient, cheaply manufactured, and have means for conveniently releasing the desired amount of oil in connection with means for leading it to surfaces on which work is being performed. A feature of my invention is the provision, in a handle of convenient shape and size, of such means for conducting oil to the desired point.

My invention is hereinafter more specifically described in connection with the ac,- companying drawings, and the essential characteristics are set forth in the claims.

In the drawings, Figure 1 is a side elevation of a multiple die stock showing my reservoir handle in position; Fig. 2 is a longitudinal axial section through such handle; Fig. 3 is a side elevation of the same showing the means for releasing the oil in an open position; Fig. 4: is a transverse central section through the die stock showing a pipe being threaded and showing the oil tube leading from the handle to the threaded portion thereof.

Handles constructed according to my invention may be used on die stocks having one or a plurality of sets of dies or on pipe cutting tools, or any like tools where it is desirable to lubricate the tool and the surface operated upon while in operation. The embodiment shown in the drawings is illustrative of any of such uses.

Referring to the drawings by numerals, the die stock shown is a box-like structure comprising a hollow frame made in two parts 5 and 6 preferably duplicates of each other and secured together by pintles 8 eX- tending through registering openings in laterally projecting ears 9, thus removably securing these parts together. 10 indicates Specification of Letters latent.

the cutting die suitably secured in position lnside these members to which access is had by separatlng the frame parts 5 and 6 and to which pipes to be threaded may bev guided by bushings such as indicated at 11 in outwardly extending sleeves 12 serving as guides for these bushings and rigidly carried by the frame parts. At the ends of the frame are provided arms 15 and 16 rigid with the frame parts 5 and 6 respec tively, and so arranged as to overlap and receive the threadedends of handles. Ordinarily substantially cylindrical members such as indicated at 18 (at the right of Fig. 1) are used and are provided with a threaded portion 19 engaging the registering threaded openings in the arms 15 and 16. As stated, this die stock may be of any suitable structure. For a more complete description of the particular one shown, reference may be had to the application of John B. Martens, die stocks, Serial No. 95,462, filed May 4:, 1916.

The construction of the handlewith which i this invention is concerned is as follows: The body or shank of the handle comprises a hollow cylindrical tubular member shown as suitably threaded at 26 for engagement with the die stock frame, and closed at its upper end by a cap member 30 having interior threads 31 cooperating with threads on the exterior of the outer end of the handle. The cap is shown as provided with flattenedside portions 32 for engagement with a wrench or other suitable tool by which it may be tightly screwed in position. The outer end of the cap is provided with a concave depression 35 extending inwardly to an axial hole which serves as a guide for a plunger 36 rigid with an outwardly extending flange 37, and between this flange and a shoulder on the inner side of the cap is a rubber or fibrous washer 38 acting to close vent openings 39'leading through the cap adjacent to the plunger 36. The outer end of the plunger normally stands beneath the outer end of the cap so that the plunger may be protected by the cap from inadvertent depression.

Screwing into the plunger 36 is an axially positioned rod l0 having on its lower end a valve head 42 provided with a beveled surface adapted to cooperate with a corre sponding valve seat in a plug 45 rigidly secured in the lower end of the tube member 25. A passage 46 is shown as surrounding the rod 40 and leading to the valve seat 'to the surface where it is required.

The tube 25 forms a reservoir which may be filled with oil by removing a small threaded plug 54 in the side of the tube and inserting the oil through the opening closed thereby. A handle may then be placed in position on the tool with which it is to be used and when used with a die stock, such as shown in the drawings, the tube 52 is turned so that it may extend to a point adjacent the dies to be used, as illustrated, for example, in Fig. l where the tub-e leads to threads on a pipe 60 which is being oper ated upon by the die stock. Here the end of this tube extends to the adjacent side of the pipe at a point where the threads are being cut, and it will be seen that when the pipe is in a vertical position, oil, released by depressing the plunger 36 opening the valve 42, will flow through the'tube 52 to the point where it is to be used coming on the surfaces where the threads are being cut and facilitating the cutting operation.

In order to bring the tube 52 to the set of dies being used, it is necessary to rotate the handle 25. It is desirable to prevent rotation of the handle after the tube 52 is positioned by means of a latch carried by the handle. This latch is shown as comprising a pivoted member 65 having nose portion 66 adapted to engage notches 67 in the frame, and urged into any of these notches by a spring indicated at 68. The latch member 65 is shown as pivoted by a. suitable bracket 69 to the side of the handle. The position of this latch is preferably on the same side of the handle 25 as that toward which the tube 52 leads so that it may serve to indicate the position of this tube, there being as many notches 67 as there are sets of dies, and spaced relative to these dies. It is apparent from Fig. 4 that it would be only necessary to swing the tube 52 around within the frame to direct oil to any of the sets of dies.

Heretofore it has been common practice with such tools to stop the cutting operation at intervals while the operator lubricated the cutting tool and surfaces by means of an oil can. This usually results in a waste of oil as more oil is put on at any one time than necessary, whereas, with my device the oil may be brought to the cutting tool as tions.

often as desired, being only necessary forthe operator'to depress the plunger with his thumb while the handle is' in a position tO'I cause the oil to run toward the cutter. Thus ing a number of separate cutting dies a handle secured to the stock for rotating the same and comprising a hollow tubular member adapted to carry oil, a tube leading from the inner end of the handle and movable so that it may be brought to a position to lead oil to any one of the dies.
